I'm running an F16V2r with differential expansion and 1 differential receiver. I'm using Xlights to sequence and FPP with 2 remotes.

I've attached a couple of pics. The 2nd pic is the way I "had" my channels set, which is correct.

However, in the 1st pic it shows how something keeps changing the start channel for universe 138 on line 11 from 32797 to 32 and it causes all the subsequent entries to "turn red". No matter how many times I correct the start channel, it keeps getting changed back to 32! I'm about ready to pull my hair out! What gives?

I saw a dialog box once that said channnel numbers had to be between 0 and 32767. So does that mean I can't have channels over 32767? If so, then I have a major problem because my channels ARE above 32767. Surely that's not all this controller can handle?

Do I need a firmware upgrade perhaps? I'm currently running 1.09.

Does anyone have any ideas about what's going on, and how to fix or overcome it?

Shouldn't the start channel of the next universe start 1+ the end channel of the previous universe? Also, why are you using blocks of 510 and not 512? I have all of my universes set in order from 1 - 32K with no gaps in blocks of 512.

Any help or advice would be greatly appreciated.

I have seen that the webpage reports one incorrect value but have not been able to track it down. If you type http://192.168.1.50/universes.xml (with your controllers ip) you will see the settings that are in the board. This will be the correct representation of what is in the board. Please ignore the bad reported value on universe page (causing all the red).

Thanks for all the responses. Yes, the universe and channel numbers are correct... I skipped a few channels/universes to allow for future expansion if needed. I didn't skip any channels in 2015 (my first year) and regretted it when I had to make unintended changes. I'm using 510 channels per universe due to some E682s in my display that require 510... and I just stuck with that for everything else for consistency.

I checked the XML and it appears to still have the correct channels (they're actually 1 less than the actual # entered, but I assume that's correct).

However, all my models with channel numbers > 32767 on the F16V2 are physically NOT working (3 of them). I doubt that's a coincidence.

What's weird is that the models on the differential receiver ARE working, and those channels are well over 32767.

So is there a numeric channel "ceiling" of 32767 on the F16V2? ...or is my issue a bug?

The lowest channel and the highest needs to be within 32K of each other. That is only limitation. So if lowest is 20K the highest must be less than 52K.

Sorry, I just saw this... went to bed after my last post. It was 1am here on the east coast.

I just thought of something that could be the cause... I have some unused ports. I have a start channel value of 1 entered for each unused port on the STRING PORTS tab. (See the attached pic) Is the controller using the value of 1 as the lowest channel, and limiting me to 32767 based on that value?

I entered a value of 1 because I'm pretty sure I read a post on this forum recommending to do that for unused channels.

If this is the cause of my issue, what channel number should I enter for these unused ports? Zero?

I'm going to double check the connections for my non-working models and play around with the controller settings a bit more. If I can't get it working I may give you a call. Thanks for the help!

I changed the start channel of all unused channels on the "string ports" tab to 26167, which is the lowest channel used by the models on the F16V2R.

I'm still having the issue where the channel on line 11 gets changed from 32797 to 32. It's totally random, though. Sometimes when I click the "E131 Configuration" tab everything is correct. Then if I click another tab & return to the E131 tab, it's changed to 32 and everything is "red". If I click the tab again, sometimes it stays changed, and sometimes it displays correctly. It's very strange. the XML file always seems correct, though, which is good.

The good news is that all my models seem to be working now. I found a couple of issues with my wiring, so I'm not sure if the wiring was the fix, or if it was the channel changes.
